Innovative, brushless motor technology - higher performance, more compact dimensions and longer life. Very high drilling progress through optimally tuned electro-pneumatic hammer work. Perform & Protect: Safe and fatigue-free working with low vibrations through special damping mechanics of motor, gear and impact mechanism. Electronic coupling for a uniformly high torque and an even longer service life. Safe use of machine by electronic motor brake. Electronic speed and stroke rate control allows a perfect adjustment to the material to be processed. Rotation and impact stop for performing light chiseling work in plaster/tiles. Modular machine design ensures fast and trouble-free service work. Powerful, bright white LED light with optimally aligned light beam. Rubberized handle, very low weight and balanced design for fatigue-free working even in longer applications. As standard in T STAK-Box II and as basic type (without batteries and charger) optimally suitable for already existing 18
